My invention relates to typewriting machines and has particular relation to certam improved features that are adapted to be em bodied in machines in which the platen and the supporting frame or carriage therefor is pivotally shiftable betweencase positions,

although the. application of certain of these features is not limited to machines of this character. The primary object of myinvention, in general, is to providecertain improved forms of carriage shifting and feeding mechanism, and ribbon vibrating and feeding mechanism adapted to be utilized in connection therewith, together with improved forms of universal frame and space barmechanism and other mechanisms and devices adapted to cooperate with the aforesaid mechanlsms.

Another important object of my invention is to provide a machine embodying the above.- identified elements, the parts of which are very economical to manufacture and to assemble and are adapted to cooperate to provide a machine of extremely sturdy and reliable construction without sacrificing those refinements which cause the machine to produce work of the highest character and the best appearance. In pursuance of this and other objects, I have developed the machine hereinafter described, and it will be apparent to those interested in such machines that my invention had reduced the number of total parts utilized, not only in the machine as a whole, but

in each of the separable mechanisms or 83- semblies composing said machine, so that the cost of building the latter is markedly less than has been the case in the past. 1

Again, I have not only reduced the number of parts, but-I have so designed the separable assemblies comprising my novel machine that the elements thereof may be produced by stamping or punchin' operations, wherefrom a substantial a ditional economy is effected.

Again, I have in many instances eliminated the various connecting levers and links which have previously been considered essential in order to produce the required movement of the operating parts in a well designed typewriter. In this regard, my machine contemplates, in man placeswhere such involved linkages have eretofore been used, an embodiment of direct contactive connections bea tween operating and operated parts; and it is to the attainment of this latter object that the invention hereinafter described is, in a large measure, directed.

Finally, inasmuch as the typewriting machine hereinafter described is substantially a nonse arable entity,having regard, of course, maybe utilized in other combinations,I have not seen fit to split up the description of the mechanism hereinafter described as might have been the case if the various novel assemblies had been separately developed without a viewto their ultimate co-relation in an entirely novel machine. In other words, because of the particular and peculiarly novel interconnection and interrelation of the parts, mysaid machine is not susceptible I have found it desirable and, as indicated,

even necessary, not only to place properlybefore the art the machine as an inventive whole but, in order to insure themaximum protection for myself, to describe and claim the machine in as few applications as possible. In pursuance of this olicy, I have hereinafter described all of the mechanism of the machine that functions in response to finger strokes and have claimed the same in this application, omitting only s ecific claims to the ty e-bar action embodie in said machine, it eing my present view that such a separation is not immicable to my interests. However, I reserve the right to incorporate said description of and claims to the-typebar action in the present application, should I find that the interrelation between the parts or the fact that various assemblies
